WIDE RANGE

THE SYSTEM Mitsubishi Heavy Industries' KXZ heat pump series with VRF-T technology is distinguished by the possibility of controlling the refrigerant temperature in the various stages of operation, improving the performance levels compared to traditional systems. KXZ is a unique system that provides an excellent performance both cooling and heating. Maximum level of design flexibility, reduction of energy consumption and advanced operating functions, centralised management of system and above all Hi-COP (KXZX), complete the profile of the KXZ series, which ensures reliability and efficiency over time.

APPLICATION IN NZEB SOLUTIONKXZ system with VRF-T technology is particularly suitable for applications on buildings constructed according to ZEB logic. In fact, the “zero-energy” buildings, realized according to ZEB logic, have the characteristics of reducing the energy consumption, but also of producing the required energy by renewable energy sources, since their goal is the self-sufficiency. To construct ZEB buildings, it is essential that energy efficiency is put as a priority condition since the construction project, taking into consideration all the components that contribute to the final result: heating, cooling, photovoltaic systems and domestic hot water, until the energy management of the entire structure. To achieve this result, one of the main application solutions is constituted by heat pumps, such as those of KXZ system with VRF-T technology.

WHY CHOOSE THE KXZ – VRF-T SYSTEM? HERE ARE 4 GOOD REASONS.

1. ENERGY SAVINGS UP TO 34%With VRF-T technology, refrigerant temperature control during the condensation and evaporation phases in the refrigerant system ensures energy savings up to 34% in cooling mode during the partial loads, compared to the traditional VRF models.

Energy savings: Max 34%Room temperature

In a traditional system, the refrigerant target pressure to be maintained is constant. As soon as room temperature reaches the temperature set by the user, the compressor is forced to decrease and increase the rpm by on-off cycles that affect the overall efficiency and performance.

KXZ system cooling operation with activation of VRF-T mod

With the new VRF-T, the refrigerant target pressure to be maintained is not constant, but adjusts proportionally to the difference between the room temperature and the desired temperature. This allows the Inverter compressors to modulate the rpm without ever stopping, thus expressing the maximum efficiency for a global energy saving operation.

Indoor units.16 types of units for a total of 91 models.The variety of types and capacities ensures an offer capable of meeting all the design and installation requirements.

Outdoor units.Up to 80 connectable indoor units. 5 product lines from 8 to 60HP (22.4~168.0 kW): Micro Compact, Micro Smart, Advanced, HiCOP and Water. Mitsubishi air conditioners with VRF-T technology all have double vertical fan and three-phase power supply. They can be installed also in twin combination, with only one refrigerant circuit. The total splitting distance reaches 1000 m.

ADVANTAGES FOR DESIGNERS

The system design phase requires flexible and advanced solutions, able to respond to each manufacturing solution.Below is a list of all the points that make KXZ - VRF-T a system equipped with all the advantages that meet new design standards.

1. HIGH SPLITTING LENGTH, FLEXIBLE DESIGN 1000 m [10~60HP

(KXZ series)]

The splitting height difference between indoor units has been increased up to 18 m, permitting the placement of indoor units on three additional storeys. The farthest indoor unit (160 m) or the total length (1000 m) contribute to the flexible design of the system.

Total length: 1000 m

REFRIGERANT CONNECTIONS

VRF-T systems are manufactured to the highest standards of quality and reliability and it is therefore essential for the installation procedures and materials to have the same qualitative features, to ensure trouble-free long-term operation. It is advisable to use high quality copper refrigerant piping, in coils or in straight, semi-rigid lengths. The copper piping should be chosen considering the higher operating pressure of R410A refrigerant gas and the increased pressure circulating in the system produced by reverse cycle operation. All materials used must comply with European standards (EN 12735). The branch pipe kits supplied must be used to connect the indoor units and the manifold kits must be used to connect the outdoor units (if necessary). It is forbidden to use standard accessories (elbow pipes, T-joints etc.). The branch pipes must be installed according to manufacturer guidelines and must allow a continuous flow of refrigerant in accordance with European standard E378:2017.All connecting welds must be made under slight nitrogen pressure to prevent the oxidation of the inner surface of the copper pipes. During installation, no accidental entry of condensate, dust or any other contaminant must be permitted. Once installation is complete, a leak test must be carried out to check for refrigerant leaks with pressurised nitrogen. The ends of the pipe must be bent and welded and an appropriate service valve affixed.

Additional refrigerant chargeOnly R410A refrigerant gas must be used, and this must be added by weight using an electronic meter. The amount of additional refrigerant must be carefully calculated according to the manufacturer’s guidelines, defined by the length and diameter of each section of the system piping.

ELECTRICAL CONNECTIONSVRF MHI systems require highly simplified electrical connections to the indoor units, thanks to a control circuit that uses 2 non-polarised conductors. The supply system has wiring that can be connected on the front, right, left or rear of the outdoor unit. For three-phase outdoor units and single phase indoor units, a separate power supply must be used. The interaction between the outdoor unit and indoor unit takes place via the control device only.

Outdoor unit power supply: three-phase, 4 wires, 380~415V Separated power supply system

CAUTION: if the RCD is dedicated solely to protecting against leakage to earth, it will be necessary to install a circuit breaker.

The maximum number of indoor units that can be connected to a signal line is 128, and it is possible to create groups of outdoor and/or indoor units connected to the same outdoor unit or to separate outdoor units, as long as they are connected to the same signal line. The signal line can also be connected by adopting the method described below (multiple connectors).

It is possible to fix the operation mode of the system (cooling or heating) using a switch (SW3-7) on the outdoor unit PC board: this enables the user to decide the operation of the system inside the building (e.g. cooling only in summer/heating only in winter), to avoid unnecessary energy waste. It is also possible to wire the control switch to a remote location (inside the building), in a control room, or even linked to an ambient thermostat.

FIXED COOLING MODE/FIXED HEATING MODE (SUMMER/WINTER SWITCH)

Priority operating mode selection You can select the following priority operation modes (for the whole

system).

1. The first unit's operating mode commands the operating mode (default setting).

The system operates according to the mode selected by the majority of units in operation, taking into consideration the greater capacity between the sum of units in cooling mode and those in heating mode. The minority operating mode is set to fan mode automatically.

“Majority” operating mode

In “Master” function, if you select the cooling mode, the units set in heating mode switch to fan mode automatically.

VRF Multi system KXZR 3-PIPE seriesHeat recovery

Simultaneous heating and coolingThese heat recovery systems work with 3 interconnecting pipes and therefore are commonly referred to as "3-pipe" systems. These systems offer both heating and cooling in a single indoor unit, based on the room conditions/requirements. The systems incorporate a highly sophisticated air conditioning control for multiple indoor areas, regardless of the cooling or heating needs, for applications where the building orientation (N, S, E, W) may result in a heat increase/loss on different sides of the same building.The range starts from a cooling capacity of 22.4 kW and goes up to 20HP with a cooling capacity of 56.0 kW. The outdoor units can also be combined in "pairs" or in "triple combination", reaching 60 HP/168.0 kW on a single system.

During defrost or during automatic compressor protection, activated every hour during heating, the heating operation stops and restarts temporarily after a specific time interval. The series is equipped with the same automatic compressor protection even in cooling mode. During this protection period, only the air flow is active and the cooling operation restarts at the end of a specific time interval.

• Where total power is higher than 130%, an additional refrigerant charge is required on site.

* With 8-34HP systems, if one or more of the FDK, FDFL, FDFU and/or FDFW series are connected to the system, the total power of the indoor units cannot exceed 130%.

Connectable indoor unitsIt is possible to connect up to 80 indoor units to the outdoor unit of greater power size. 16 different types of indoor units are available, visible or recessed, in different sizes, for a total of 91 overall possibilities.

Heat recovery systems

The KXZR series has an an extensible system design, considering a heating range at low temperature conditions down to -20°C, and a cooling range up to 46°C (previous model: 43°C).

HEATING

Cooling

The interconnection piping system has a unique arrangement with two of the interconnecting pipes passing through an PFD distribution controller and the third tube connected directly to each indoor unit from the main pipe path. This reduces installation times and the number of braze-welded connections on the site. The PFD distribution controllers are available for single connection or as a 4-way combined PFD connection, with each connected unit characterised by independent cooling or heating.

This model is not suitable for the use of annual cooling operations, for example for the server room, especially in areas where the outdoor air temperature falls below 5°C. In case of mixed operation in cooling and heating with outdoor air temperature lower than 5°C, the cooling power can decrease with respect to the operating power in cooling mode only.

Continuous control of the heating power reduces compressor frequency by modulating it at the minimum speed for a longer period of time. The total number of defrost cycles is considerably reduced, increasing the total power delivered and ensuring high comfort.

Improved cooling capacity at low outdoor temperatureThe small partitions of the exchanger and the internal pressure control allow the outdoor unit to operate in cooling mode even in low ambient temperature conditions, for greater capacity in very low environmental conditions (-5°C) compared to the previous model.

Exchanger resizing allows for better control of the pressure at low load regimes.

In the previous model, in the presence of a strong heating demands and simultaneous low cooling demands in low ambient temperature conditions, the pressure control is adjusted to maintain a greater heating power compared to a sufficient cooling power.The new heat exchanger and pressure control adopted in the KXZR series has simultaneously improved its capacity for both heating and cooling power *. * The cooling system has priority for the required heating mode compared to a very low cooling demand, where most of the indoor units are used in heating mode.

REFRIGERANT CONNECTIONSVRF-T systems are manufactured to the highest standards of quality and reliability and it is therefore essential for the installation procedures and materials to have the same qualitative features, to ensure trouble-free long-term operation. It is advisable to use high quality copper refrigerant piping, in coils or in straight, semi-rigid lengths. The copper piping should be chosen considering the higher operating pressure of R410A refrigerant gas and the increased pressure circulating in the system produced by reverse cycle operation. All materials used must comply with European standards (EN 12735). The branch pipe kits supplied must be used to connect the indoor units and the manifold kits must be used to connect the outdoor units (if necessary). It is forbidden to use standard accessories (elbow pipes, T-joints etc.). The branch pipes must be installed according to manufacturer guidelines and must allow a continuous flow of refrigerant in accordance with European standard E378:2017.All connecting welds must be made under slight nitrogen pressure to prevent the oxidation of the inner surface of the copper pipes. During installation, no accidental entry of condensate, dust or any other contaminant must be permitted. Once installation is complete, a leak test must be carried out to check for refrigerant leaks with pressurised nitrogen. The ends of the pipe must be bent and welded and an appropriate service valve affixed.

Additional refrigerant chargeOnly R410A refrigerant gas must be used, and this must be added by weight using an electronic meter. The amount of additional refrigerant must be carefully calculated according to the manufacturer’s guidelines, defined by the length and diameter of each section of the system piping.

ELECTRICAL CONNECTIONSVRF MHI systems require highly simplified electrical connections to the indoor units, thanks to a control circuit that uses 2 non-polarised conductors. The supply system has wiring that can be connected on the front, right, left or rear of the outdoor unit. For three-phase outdoor units and single phase indoor units, a separate power supply must be used. The interaction between the outdoor unit and indoor unit takes place via the control device only.

PFD 1124-E, PFD 1804-E, PFD 2804-E, PFD 1124X4-E

Designed and manufactured at Mitsubishi Heavy Industries specialist research laboratories, the PFD flow divider now enables all indoor units to be integrated into an air conditioning network, to switch from cooling mode to heating mode, or vice versa, while the whole system remains operational, thus preventing costly power on and power off cycles. In case of conversion from cooling mode to heating mode and vice versa, by simply combining the indoor unit and the PFD box, the sound level is reduced, thanks to the shutdown of the compressor which, however, does not lead to any reduction in capacity. The risk of refrigerant leaks is reduced by changing the welding method between the refrigerant piping and the PFD box. By using the optional extension cable for the PFD box, equipped with a connector, it is possible to further separate the PFD box from the indoor unit. This enables a reduction in sound level caused by the PDF box and the flow of refrigerant.

Ease of installationThe design PFD flow divider makes it possible to connect the liquid line of the indoor unit directly from the liquid piping coming from the outdoor unit, therefore bypassing the PFD. This reduces the number of connections per indoor unit and, consequently, installation times and costs. Groups of indoor units up to a total capacity of 44.8 kW (11.2 kW x 4) can be connected to a single PFD by means of branch pipes, therefore the units in this group will all operate in the same mode,cooling or heating. The PFD1124X4-E 4-pipe control device, able to connect up to 4 indoor units with individual operation - simultaneous cooling or heating - is also available. The PFD flow divider is connected to the indoor unit with a 3-wire signal cable via a relay kit (supplied) to be installed within a maximum distance of 2 metres. The indoor unit, on the other hand, can be installed up to a distance of 40 m. The PFD electric power supply may derive directly from the indoor unit or from other sources.

The simple and flexible solution for increasing comfort in buildings, with high energy performance

DXA-DU-E: condensate drain kit up to 60 cm (optional)

The SAF DX units, available in 5 power ratings, is a device designed to increase the comfort capacity of KXZ systems located in buildings, with their high quality profile in terms of energy.Extremely flexible in that it operates independently from the regenerator, it is able to optimise temperature of the primary air taken in by the SAF regenerators or by similar systems installed in the building. Its compact size and installation separate from the fan unit, solve numerous installation problems; the lack of moving parts makes it possible to install the unit in a wider range of locations and reduces noise to a minimum.

•CanbecombinedwithallindoorandoutdoorunitsintheKXZrange*.

Note* If using the SAF DX, the load index available for the outdoor unit is reduced to 100% of

the rated capacity.** The available options vary depending on configurations.

The SAF DX post-treatment is not intended to replace an indoor unit.
